I sold a system and installed it yesterday with 5230s.

They went with the 5230 because they wanted the full duplex, high quality speakerphone.

The customer hasn't said anything yet but they sound real tinny to me. Background music, voicemail key...

My 5243 sounds fantastic. It's All About That Bass, No Treble. I thought they had the same speaker system?

System installed is a 7200S with an OAS card and Samsung Ubigate switches. Software version on system is 4.8x (I forget)
